Report to show duration between each status change

You should make the "Status Change" a child table of the the main Job.  

Then you can do it all within QuickBase without notifications, or sync.  Then you can easily see the duration of each status right in one spot. 
You can also make the status change, but clicking "one" button.   You can also see who, and when status changed.  

Its a much cleaner solution, happens instantly, much easier to maintain, and is not dependent on outside systems.
